Kernel panic - not syncing: Kernel exception

Follow-ups

--- Mike Frysinger 2008-11-02 02:19:04

coincidentally, my kernel was built with debugging symbols ...

--- Mingquan Pan 2008-11-20 05:06:08

yeah, I also see this bug on bf537 when doing netperf testing.

The kernel goes to panic when the netserver on the host is killed when the

testing is finished.

The kernel that is running netperf testing doesn't use l1 and set like

following:

# CONFIG_BFIN_MAC_USE_L1 is not set

CONFIG_BFIN_TX_DESC_NUM=100

CONFIG_BFIN_RX_DESC_NUM=500

This bug is introduced aroud the upgrade at the end of Oct.
